Specification forming part of Letters Patent No. 59,039, dated October 23, 1866.

To all whom it may concern:

Be it known that we, WILLIAM M. LANE- HART and J osnrn 0. KING, of Gook stown, in

the county of Fayette and State of Pennsylva' nia, have invented a new and useful Improvement in Sand-Washers; and we do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the binin g therewith apparatus to carry the sand or minerals from one cistern to another, and, finally, to discharge it when washed, and in providing it with a fresh supply of water whenever requisite as the process of washing goes on.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

In manufacturing we use any known materials adapted to the purpose. The cisterns a a we usually construct open at the top, and of sufficient size to accomplish the objects hereinafter set forth, and with a bottom concave or inclined from the outer edge toward the lower ends of the elevators c 0, so that the elevators shall work closely thereto. The sand or pulverized mineral is received, usually, from a riddle or sieve in the cistern 0!, where, with a plentiful supply of water, the loam or other light earthy or foreign matter is separated from the sand, the latter sinking to the bottom of the cistern, and the former being carried off with the wastewater at the notch or aperture 1). The elevator 0, made usually of chains, with metal buckets 0 attached, being set in motion by power applied to the shaft 8, either by crank at s or otherwise, carries the sand thus washed up the inclined trough d, which is so constructed under the elevator c that the buckets 0 shall work closely therein. The sand is thus discharged into the box 0, where it receives fresh water in any desirable quantity from the horizontal trough f through the gate g. The 'fresh water thus furnished carries the sand down the spout m to the cistern a, where a similar washing process takes place, the sand sinking to the bottom, and light foreign matter being carried off by the waste water at the notch or aperture b, as before. The revolution of the shaft 8 drives the next and similarly-constructed elevator c, fitted with buckets 0, as before, and all succeeding elevators (if more are used) in the same manner and with the same results as above described, the sand being carried up the inclined trough d" to the box e, receiving fresh water at the gate 9, to be again Washeddown,

- if so desired, and the washer be so constructed.

' We make the washers with any desirable number of elevators, though three or four are usually sufficient.

After passing through any desirable number of washings, as above described, the sand is carried down the spout a to an elevator, 0, also fitted with buckets 0, which works in a re verse direction, the direction being changed by the gear-wheels w 00, and motion communi cated thence by the belting y to the shaft z and elevator 0, or by other equivalent mechanical devices. By this elevator 0 the sand is can ried up a trough, h, similar in its construction to the inclined trough d above described, and finally discharged into any desirable receptacle prepared for the purpose. By these devices the sand is washed of all its lighter impurities and discharged from the water entirely by mechanical appliances. It is thus rendered fit for use for manufacturing purposes, particularly in the manufacture of glass, of which it is a necessary ingredient.

The water is usually supplied to the cistern a and horizontal trough f by pumps connected with and worked by machinery, or by any other means ordinarily employed for such pur pose. The supply of water from the trough f (the same being constructed with one or more compartments, as may be preferred) is regulated by opening the gates g g more or less, as may be desired. -We also extend the use of this invention to the cleansing of pulverized minerals, especially when mixed with sand or earthy or other light foreign matter. 1

We do not restrict ourselvesto the particular form of the elevators c c 0, as described,

norof thebuckets 0, nor to the particular mode of carrying the sand from the cisterns a a up the troughs d (1, as we accomplish the same results by using a flat or scoop-shaped bucket, and, when using one of the latter shape, by working the elevators 0 c o in the same or reverse direction. The elevator 0 is also equally efficacious, discharging in any direction.

What we claim as our invention, and desire to secure by Letters Patent, is

1. The construction and use of, the cistern 0!, in combination with an apparatus for washing and raising sand, substantially in the manner and for the purposes above set forth.

2. The cisterns a a, one or more, in combination with a corresponding number of elevators and spouts and the trough f, the whole being constructed and arranged substantially in the manner and for the purposes above set forth.

In testimony whereof we, the said WILLIAM M. LANEHARTand JOSEPH 0. KING, have hereunto set our hands.
